Influence of mechanical action on the development of electrodynamic phenomena in ionized gas

Abstract A special feature of this work is the study of the effect of mechanical mode disturbances on the discharge and plasma flow. It is found that the mechanical impact of a shock wave in a dense gas in an electric field of high intensity almost to the ignition voltage causes an electrical “breakdown” as current peaks. The ultrasonic effect on the flow of the reacting plasma of the air as shown by the analytical study of the thin layer of the plasma flow changes the type of flow.

Abstract A comparison of the effects of various time periods of ultraviolet light on the formation of rearrangement products of parathion is presented. Twelve products were separated and identified by thin layer chromatography in 4 systems, and were confirmed by infrared spectroscopy, when possible. The effect of 2 solvents, methanol and acetone, on the formation and percentage composition of photoalteration products of parathion from high-intensity ultraviolet light is also discussed. Retention times are given for each component from gas chromatography by electron capture and flame photometric detection.

Insight Into

The solution for the flow of a fully ionized gas over a wedge of finite angle is known for the case when the applied magnetic field is aligned with the incident stream. In this flow there are current sheets on the surfaces of the wedge. When the magnetic field is allowed to deviate slightly from the stream, the current sheets may move into the gas and become shock waves. The magnetic fields adjacent to the wedge above and below it have to be matched. A perturbation method is introduced by means of which expressions for the unknown quantities in the different regions may be determined when there are four shocks attached to the wedge. The results give insight into the manner in which the shock-wave pattern develops as the obliquity of the magnetic field to the stream increases. The question of the stability of the shock waves is also examined.

General Method

SummaryThis note discusses changes in the state of a gas flowing in a duct of constant area. In the past, changes, such as normal shock waves, combustion and other phenomena, which are defined by the equations of energy, conservation of momentum and mass flow, have each been treated on their merits. In this note a method is developed whereby all phenomena governed by these three equations can be solved by a single general method. The method rests on the derivation of a parameter which is unaltered in value by the change, in all cases where the total temperature is constant. A shock wave is an example of such a discontinuity. In problems of heat addition or extraction, the parameter changes its value only because of the change in total temperature. The change in total temperature may be calculated from the known quantity of heat added or extracted.The parameters derived are useful in showing how problems of this type should be attacked analytically. With oblique waves it is easy to derive a relation between the normal velocities before and after the wave, and it is probable that this relationship has not been published before.
